Effectiveness of Bio-K+ for the prevention of Clostridioides difficile infection: Stepped-wedge cluster-randomized controlled trial.

OBJECTIVE: To evaluate the impact of administering probiotics to prevent Clostridioides difficile infection (CDI) among patients receiving therapeutic antibiotics. DESIGN: Stepped-wedge cluster-randomized trial between September 1, 2016, and August 31, 2019. SETTING: This study was conducted in 4 acute-care hospitals across an integrated health region. PATIENTS: Hospitalized patients, aged ≥55 years. METHODS: Patients were given 2 probiotic capsules daily (Bio-K+, Laval, Quebec, Canada), containing 50 billion colony-forming units of Lactobacillus acidophilus CL1285, L. casei LBC80R, and L. rhamnosus CLR2. We measured hospital-acquired CDI (HA-CDI) and the number of positive C. difficile tests per 10,000 patient days as well as adherence to administration of Bio-K+ within 48 and 72 hours of antibiotic administration. Mixed-effects generalized linear models, adjusted for influenza admissions and facility characteristics, were used to evaluate the impact of the intervention on outcomes. RESULTS: Overall adherence of Bio-K+ administration ranged from 76.9% to 84.6% when stratified by facility and periods. Rates of adherence to administration within 48 and 72 hours of antibiotic treatment were 60.2% -71.4% and 66.7%-75.8%, respectively. In the adjusted analysis, there was no change in HA-CDI (incidence rate ratio [IRR], 0.92; 95% confidence interval [CI], 0.68-1.23) or C. difficile positivity rate (IRR, 1.05; 95% CI, 0.89-1.24). Discharged patients may not have received a complete course of Bio-K+. Our hospitals had a low baseline incidence of HA-CDI. Patients who did not receive Bio-K+ may have differential risks of acquiring CDI, introducing selection bias. CONCLUSIONS: Hospitals considering probiotics as a primary prevention strategy should consider the baseline incidence of HA-CDI in their population and timing of probiotics relative to the start of antimicrobial administration.

Multi-disciplinary supportive end of life care in long-term care: an integrative approach to improving end of life.

BACKGROUND: Optimal supportive end of life care for frail, older adults in long term care (LTC) homes involves symptom management, family participation, advance care plans, and organizational support. This 2-phase study aimed to combine multi-disciplinary opinions, build group consensus, and identify the top interventions needed to develop a supportive end of life care strategy for LTC. METHODS: A consensus-building approach was undertaken in 2 Phases. The first phase deployed modified Delphi questionnaires to address and transform diverse opinions into group consensus. The second phase explored and prioritized the interventions needed to develop a supportive end of life care strategy for LTC. Development of the Delphi questionnaire was based on findings from published results of physician perspectives of barriers and facilitators to optimal supportive end of life care in LTC, a literature search of palliative care models in LTC, and published results of patient, family and nursing perspectives of supportive end of life care in long term care. The second phase involved World Café Style workshop discussions. A multi-disciplinary purposive sample of individuals inclusive of physicians; staff, administrators, residents, family members, and content experts in palliative care, and researchers in geriatrics and gerontology participated in round one of the modified Delphi questionnaire. A second purposive sample derived from round one participants completed the second round of the modified Delphi questionnaire. A third purposive sample (including participants from the Delphi panel) then convened to identify the top priorities needed to develop a supportive end-of-life care strategy for LTC. RESULTS: 19 participants rated 75 statements on a 9-point Likert scale during the first round of the modified Delphi questionnaire. 11 participants (participation rate 58 %) completed the second round of the modified Delphi questionnaire and reached consensus on the inclusion of 71candidate statements. 35 multidisciplinary participants discussed the 71 statements remaining and prioritized the top clinical practice, communication, and policy interventions needed to develop a supportive end of life strategy for LTC. CONCLUSIONS: Multi-disciplinary stakeholders identified and prioritized the top interventions needed to develop a 5-point supportive end of life care strategy for LTC.

Diagnosis, treatment and management of apathy in Parkinson's disease: a scoping review.

OBJECTIVE: To conduct a scoping review of the literature on apathy in Parkinson's disease (PD), to better understand how apathy in Parkinson's disease is diagnosed, treated and managed. METHODS: MEDLINE, Embase, PsycINFO, CINAHL, Cochrane Central Register of Control Trials and Cochrane Database of Systematic Reviews were searched to 17 May 2017. An updated review was run from 17 May 2017 to 28 January 2019. The grey literature was searched using the CADTH Grey Matters tool. Original peer-reviewed research was included if it included individuals with PD and apathy. Non-original data was only included if it was in the form of meta-analysis. All information regarding diagnosis, treatment and management of PD was extracted. Citation screening and extraction were performed in duplicate. RESULTS: From 11 375 citations, 362 articles were included in the final review. The majority of included studies focussed on prevalence, with few studies examining treatment. Twenty screening tools for apathy were identified. Fifty per cent of treatment studies were randomised control trials (RCTs). RCTs applied treatment methods including: exercise, mindfulness, rotigotine (Neupro) transdermal patch and rivastigmine (Exelon). CONCLUSIONS: This review identified a large body of literature describing current knowledge on diagnosing, treating and managing apathy in PD. Future research should aim to detect an ideal screening tool for apathy in PD, to identify the best treatment options for apathy and the variety of comorbidities it may present with and finally aim to better understand postoperative apathy in those with deep brain stimulation.

Comparisons of Interventions for Preventing Falls in Older Adults: A Systematic Review and Meta-analysis.

Importance: Falls result in substantial burden for patients and health care systems, and given the aging of the population worldwide, the incidence of falls continues to rise. Objective: To assess the potential effectiveness of interventions for preventing falls. Data Sources: MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Ageline databases from inception until April 2017. Reference lists of included studies were scanned. Study Selection: Randomized clinical trials (RCTs) of fall-prevention interventions for participants aged 65 years and older. Data Extraction and Synthesis: Pairs of reviewers independently screened the studies, abstracted data, and appraised risk of bias. Pairwise meta-analysis and network meta-analysis were conducted. Main Outcomes and Measures: Injurious falls and fall-related hospitalizations. Results: A total of 283 RCTs (159 910 participants; mean age, 78.1 years; 74% women) were included after screening of 10 650 titles and abstracts and 1210 full-text articles. Network meta-analysis (including 54 RCTs, 41 596 participants, 39 interventions plus usual care) suggested that the following interventions, when compared with usual care, were associated with reductions in injurious falls: exercise (odds ratio [OR], 0.51 [95% CI, 0.33 to 0.79]; absolute risk difference [ARD], -0.67 [95% CI, -1.10 to -0.24]); combined exercise and vision assessment and treatment (OR, 0.17 [95% CI, 0.07 to 0.38]; ARD, -1.79 [95% CI, -2.63 to -0.96]); combined exercise, vision assessment and treatment, and environmental assessment and modification (OR, 0.30 [95% CI, 0.13 to 0.70]; ARD, -1.19 [95% CI, -2.04 to -0.35]); and combined clinic-level quality improvement strategies (eg, case management), multifactorial assessment and treatment (eg, comprehensive geriatric assessment), calcium supplementation, and vitamin D supplementation (OR, 0.12 [95% CI, 0.03 to 0.55]; ARD, -2.08 [95% CI, -3.56 to -0.60]). Pairwise meta-analyses for fall-related hospitalizations (2 RCTs; 516 participants) showed no significant association between combined clinic- and patient-level quality improvement strategies and multifactorial assessment and treatment relative to usual care (OR, 0.78 [95% CI, 0.33 to 1.81]). Conclusions and Relevance: Exercise alone and various combinations of interventions were associated with lower risk of injurious falls compared with usual care. Choice of fall-prevention intervention may depend on patient and caregiver values and preferences.

Screening for Frailty in Canada's Health Care System: A Time for Action.

As Canada's population ages, frailty - with its increased risk of functional decline, deterioration in health status, and death - will become increasingly common. The physiology of frailty reflects its multisystem, multi-organ origins. About a quarter of Canadians over age 65 are frail, increasing to over half in those older than 85. Our health care system is organized around single-organ systems, impairing our ability to effectively treat people having multiple disorders and functional limitations. To address frailty, we must recognize when it occurs, increase awareness of its significance, develop holistic models of care, and generate better evidence for its treatment. Recognizing how frailty impacts lifespan will allow for integration of care goals into treatment options. Different settings in the Canadian health care system will require different strategies and tools to assess frailty. Given the magnitude of challenges frailty poses for the health care system as currently organized, policy changes will be essential.

Systematic review of recent dementia practice guidelines.

BACKGROUND: dementia is a highly prevalent acquired cognitive disorder that interferes with activities of daily living, relationships and quality of life. Recognition and effective management strategies are necessary to provide comprehensive care for these patients and their families. High-quality clinical practice guidelines can improve the quality and consistency of care in all aspects of dementia diagnosis and management by clarifying interventions supported by sound evidence and by alerting clinicians to interventions without proven benefit. OBJECTIVE: we aimed to offer a synthesis of existing practice recommendations for the diagnosis and management of dementia, based upon moderate-to-high quality dementia guidelines. METHODS: we performed a systematic search in EMBASE and MEDLINE as well as the grey literature for guidelines produced between 2008 and 2013. RESULTS: thirty-nine retrieved practice guidelines were included for quality appraisal by the Appraisal of Guidelines Research and Evaluation II (AGREE-II) tool, performed by two independent reviewers. From the 12 moderate-to-high quality guidelines included, specific practice recommendations for the diagnosis and/or management of any aspect of dementia were extracted for comparison based upon the level of evidence and strength of recommendation. CONCLUSION: there was a general agreement between guidelines for many practice recommendations. However, direct comparisons between guidelines were challenging due to variations in grading schemes.

Effect of Nutrients, Dietary Supplements and Vitamins on Cognition: a Systematic Review and Meta-Analysis of Randomized Controlled Trials.

BACKGROUND: Observational studies have suggested that various nutrients, dietary supplements, and vitamins may delay the onset of age-associated cognitive decline and dementia. We systematically reviewed recent randomized controlled trials investigating the effect of nutritional interventions on cognitive performance in older non-demented adults. METHODS: We searched MEDLINE, CINAHL, Embase, and the Cochrane Library for articles published between 2003 and 2013. We included randomized trials of ≥ 3 months' duration that examined the cognitive effects of a nutritional intervention in non-demented adults > 40 years of age. Meta-analyses were done when sufficient trials were available. RESULTS: Twenty-four trials met inclusion criteria (six omega-3 fatty acids, seven B vitamins, three vitamin E, eight other interventions). In the meta-analyses, omega-3 fatty acids showed no significant effect on Mini-Mental State Examination (MMSE) scores (four trials, mean difference 0.06, 95% CI -0.08 - 0.19) or digit span forward (three trials, mean difference -0.02, 95% CI -0.30 - 0.25), while B vitamins showed no significant effect on MMSE scores (three trials, mean difference 0.02, 95% CI -0.22 - 0.25). None of the vitamin E studies reported significant effects on cognitive outcomes. Among the other nutritional interventions, statistically significant differences between the intervention and control groups on at least one cognitive domain were found in single studies of green tea extract, Concord grape juice, chromium picolinate, beta-carotene, two different combinations of multiple vitamins, and a dietary approach developed for the control of hypertension. CONCLUSIONS: Omega-3 fatty acids, B vitamins, and vitamin E supplementation did not affect cognition in non-demented middle-aged and older adults. Other nutritional interventions require further evaluation before their use can be advocated for the prevention of age-associated cognitive decline and dementia.

Management of urinary incontinence in women: scientific review.

CONTEXT: Urinary incontinence is a common health problem among women that negatively impacts quality of life. Therefore, it is important that primary care physicians have an understanding of how to manage urinary incontinence effectively. OBJECTIVE: To review the most recent, high-quality evidence regarding the etiology and management of urinary incontinence in women. DATA SOURCES AND STUDY SELECTION: Searches of MEDLINE, EMBASE, The Cochrane Library, and the ACP Journal Club were performed to identify English-language articles published between 1998-2003 that focused on the etiology or treatment of urinary incontinence in adult women. The references of each retrieved article were reviewed and an expert in the field was contacted to identify additional relevant articles. DATA EXTRACTION: Using a combination of more than 80 search terms, we included articles of etiology that were cohort studies, case-control studies, cross-sectional studies, or systematic reviews of cohort, case-control, and/or cross-sectional studies. Studies of treatment had to be randomized controlled trials or systematic reviews of randomized controlled trials. The quality of each article was assessed independently by each author and inclusion (n = 66) was determined by consensus. DATA SYNTHESIS: Multiple factors have been found to be associated with urinary incontinence, some of which are amenable to modification. Factors associated with incontinence include age, white race, higher educational attainment, pregnancy-related factors, gynecological factors, urological and gastrointestinal tract factors, comorbid diseases, higher body mass index, medications, smoking, caffeine, and functional impairment. There are several effective nonpharmacological treatments including pelvic floor muscle training, electrical stimulation, bladder training, and prompted voiding. Anticholinergic drugs are effective in the treatment of urge urinary incontinence. Several surgical interventions are effective in the management of stress incontinence, including open retropubic colposuspension and suburethral sling procedure. CONCLUSION: Urinary incontinence in women is an important public health concern, and effective treatment options exist.

Management of urinary incontinence in women: clinical applications.

Urinary incontinence, defined as involuntary loss of urine, is a common health problem among women. The prevalence rate is between 12% and 55% for having ever experienced urinary incontinence. It is associated with poor self-rated health, impaired quality of life, social isolation, and depressive symptoms. However, physicians are usually not the ones to initiate discussion about incontinence with their patients. We present clinical cases to illustrate common scenarios in which a physician may be able to help a female patient manage her urinary incontinence by specifically addressing associated factors and offering treatments to improve or possibly even cure her symptoms. Several evidence-based effective nonpharmacological, pharmacological, and surgical treatment options are outlined.
